气态甲醛对仓储害虫具有防治作用。采用动态气体灌流染毒装置模拟仓储环境,探讨随染毒时间的推移,不同微量浓度的甲醛对仓储害虫的致死效果。结果表明,一定浓度的气态甲醛对仓储害虫具有良好的杀灭作用,可以选用在国家行业标准允许范围内含量的甲醛面板作储藏柜材料。
Formaldehyde formaldehyde has a preventive effect on storage pests. Dynamic gas perfusion was used to simulate the storage environment, and the lethal effect of different concentrations of formaldehyde on storage pests was discussed with the passage of exposure time. The results showed that a certain concentration of gaseous formaldehyde has a good killing effect on storage pests. Formaldehyde panels can be selected as materials for the storage cabinets that are permitted by the national industry standards.
